    It's hyperflash and can be fixed using a sequence of power ups/downs along with switching the turn signal. Based on the year model of course. If you use the search tab and type in "hyperflash" you'll find the fix

    1. Turn key on
    2. Press and hold the hazard button for 30 seconds
    3. The cluster lights will flash confirming the calibration has been successful."

    The above worked for me on my 2014 RT-Ltd.
    Lamont has also posted a video on YouTube that has 1 extra step if the above doesn't work for you. Just search RT hyper flash.
